IMPROVEMENT IN DCVETAILING-MACHINES.

Specification forming part of Letters Patent No. 123,137, dated January30, 1872.

SPEGIEICATIQN.

I, DANIEL WHITLOCK, of Newark. in the county of Essex and State of NewJersey, have invented certain Improvements in Dovetailing-Machihes, ofwhich thefollowing is a speciflcation:

My invention relates to constructing the bed upon Which the stiles andrails lay to be dovetailed with positive bevels requiring 11o tiltingnor shifting fences, needing only adjustment up or down to admit ofdii'erent thickness of the stun" for the sash.

In the accompanying drawing, Figure l is the machine in perspective.Fig. 2 is an end View of the sliding bed and of the adjustable shelvesattached to its sides. Fig. 3 is one side of the bed With the parallelshelf attached on a larger scale than Fig. l. Fig. 4L is the other sideof the bed with the inclined shelf in connection. A Fig. 5 is a stile,and Fig. 6 a meeting rail.

A is a pillar to which the slides B are secured. Any other suitablesupport for those slides can be used. G is the main bed sliding freelyon B, having right and left bevels on the upper side of its bottom. D l2 3 are cutters, technically turned Wabbling, because of their inclineon their shafts E. Gris aparallel shelf adjustable up or down, attachedto one side of the bed piece C. H is an inclined adjustable shelflattached to the other side of C. Stiles are laid on H, and on being madeto pass cutter D 2, first, with one side up and then the other have thefemale dovetail formed in the end. Meeting-rails laid iirst on oneincline and then on the other in the bed C, have the male or pindovetail formed on their ends by being' made to pass cutter D l. For theparallel cutting next the bevel-edge of the meetin g-rail, shelf G andcutter D 3 are provided.

Thus, Without any tilting or shifting of beds or fences, and Withoutchange of inclines in the beds or rests, the needed process is completedby hand-shifting rails and stiles, and hand-sliding of the bed andshelves upon the rails B.

What I claim as my improvement is The bed C, shelves Gand H,constructed, combined, and arranged, as and for the purpose specifiedand shown.
